    OK I got my lift on last fall, I got 6.5" in the front and 5" in the rear over the stock saggy springs from my front and rear BDS springs (rear lift includes a zerorate). The top of the wheel wells started out at 36.5" at all four corners and went to 43" front and 41.5" (with the zerorate) in the rear.
    Details...

    4" BDS front springs, ORD shackles, 3* shims, ORD greaseable bushings, ford towers, Superlift driveshaft spacer

    4" BDS rear springs, with a zerorate and 3*shim, ORD greaseable bushings, HD shackles

    1.125" body lift (custom blocks), poly bushings

    Does this seem right for 35's to have this much clearence on 4" of lift, 1" body lift and no fender trimming?

    (there's a raised steering arm on here but the drag link still angles down just a bit /forums/images/graemlins/thinking.gif)


    What do you think? Is that 4" spring and 1" body lift or are the front spring a little more? /forums/images/graemlins/dunno.gif


    ***********************************************************
    UPDATE... I visited the BDS page today and seen their listings for lifts and they dont have a 5.5" spring like I remember seeing before. BUT the parts list

    4" Front/ 4" Rear
    Front Leaf Springs
    Rear Leaf Springs
    1/2 Ton Vehicle Only
    2 001401 Front Springs <---------------------
    2 001409 Rear Spring 52" Eye to Eye
    2 55620 Front Standard Shock
    2 55639 Rear Shock


    Notice anything

    Same numbers on my springs as there is for the 4"/4" kit /forums/images/graemlins/histerical.gif
    Well its a TALL 4" kit /forums/images/graemlins/whistling.gif

    When I had my 4" Rancho lift on mine, the drag link was dead level.

    I'd say that you have closer to 5-5.5" of lift as you said.

    Take that rig out and flex it a few times, get them leaves broke in!!

    I like to the see the frame in the wheel well but not under the rockers. The lift and tires suits me but I kind of wish I spent the other $60 and got 37's /forums/images/graemlins/doah.gif I still need to regear so it would have been just as easy to go 4.88 instead of 4.56's /forums/images/graemlins/dunno.gif

    nah, I've crunched the numbers many times and I originally was going 4.10's, then after chatting with you at the Badlands I figured I'd try 4.56's, they are a little higher RPM than I want to run on the highway, dont want to loose to much gas mileage.

    Re: Lift tire question of a different kind....

    4.88's with 37's will give you just about the same highway RPM as 4.56's and 35's, which is nearly the same as 3.73's and the weenie 29's that most rigs left the factory with. /forums/images/graemlins/eek.gif Even running the 4.88's with the 35's will only raise your RPM at 75 MPH by about 160 RPM over 4.56's. /forums/images/graemlins/wink.gif

    Re: Lift tire question of a different kind....

    Yeah my truck had 3.08's and 31's since I can remember, then I ran 32's with the 3.08's before I knew better. A jump to 4.56's and 35 is going to be about 500-600RPM higher cruising on the highway... Thats a pretty big jump for a 100K mile motor. Around Indy even if your doing 75MPH in the center lane your still getting passed on both sides. So I dont want to have to run 3000RPM to go around the city. I think 4.10's would have been pushing (not pushing as bad as 3.08's and 32 which is ran fine at), but 4.56's should give it a little more breathing room without beating it to hard trying to run on the highway.

    35's and 4.10 are 50PRMs lower than 31's and 3.73's.

    first speed is 65MPH / 75MPH
    29in/3.08's - 1623.7 / 1873.5
    31's/3.73's - 1839.5 / 2122.5 [this is what my plow truck has]
    32's/3.08's - 1471.5 / 1697.9 [been running this setup for 4 years and seems ok]
    35's/4.10's - 1790.9 / 2066.4 [this was my original choice]
    35's/4.56's - 1991.8 / 2298.2 [+200RPM above the 4.10's, +500PRM from current gearing /forums/images/graemlins/thinking.gif that should be enough of a jump to cruise happily)
    35's/4.88's - 2131.6 / 2459.5

    I have 24.5" in the rear with a 4" block only.
    the front is 27.6" to center of hub, 4" pro comps and a .75" zero rate with a DIESEL. so you should be 1.125" taller for the body lift.
